To [I/ZZ whom it may concern.-

Be it known that 1, JOHN LOUIS CANTELO, a subject of the Queen of Great Britain, residing at Liverpool, in the county of Lancaster, in the Kingdom of England, have invented certain new anduseful Improvements in Music-Recorders for Pianofortes or other Similarly Keyed Musical Instruments, of which the following is a specification.

The object of my invention is to improve and render more generally useful and effective that class of recording attachments for pianofortes or other musical instruments having keyboards of similar form which enable a player to register the score of a musical composition on a running band of paper in such manner that it may be readily transcribed afterward into the ordinary musical notation.

In the accompanying drawings, Figure 1 is an elevation of the recording apparatus, looking from the back of the piano-keys, the paper-roll and motor-train being removed and other parts broken away. Fig. 2 is a plan View of same with the paper-roll, motor-train, and flying governor in place. Fig. 3 is a side view of the motor-train. Figs. at and 5 show the construction of the governor; Figs. 6 and 7, somewhat modified arrangements of same. Fig. 8 is a vertical section of the frame-board of the apparatus, showing also the manner in which it is attached to the piano and the means employed to impress note-marks upon the paper band. Fig. 9 is a side view of the means by which the time-fractions are impressed at the end of each measure. Fig. 10 is a plan view of a spring-arm, of which two pairs are used to attach the frame-board to the piano. Fig. 11 shows the ratchet and detent which stop and start the train. Fig. 12 is a front view, with the frame-board removed, of the sliding indices, with the time beating, regulating, and impressing parts to which they are related. Figs. 13 and 14 show a method of striking the time-beats audibly. Figs. 15 and 16 show an alternative method of transmitting movement to the time-printing lever at the end of ameasure. Fig. 17 shows a variation which may he sometimes desirable in the relative positions of the paper-roll and the rollers connected with the feeding,1narking, and ruling of the paper band.

In carrying out my invention I provide support for the mechanism by a frame-board A, which may be of wood, papier-mach'e, or other suitable material, its suitability consist ing in its possession of the requisite strength, combined with the qualities of lightness in weight, durability, and freedom from any considerable tendency to warp under the influence of change in the temperature or moisture of the air. When in position, this board stands with the ends of its lower edge resting on the key-blocks of the piano, one of which is shown and marked B in Fig.8. The board is placed as near the backs of the keys as possible and is held in its edgewise position with sufficient firmness by arms G G, Figs. 8 and 10, which, with their connected parts, are practically in duplicate at each end of the board. The arms G G are rigidly connected by a rod N, upon which is coiled a spring L, having one of its ends turned into a hole in an angle-plate M, as shown by the dotted lines in Fig. 10, and its other end secured in any suitable convenient manner to the rod N or to one of the arms GG.- Through the free ends of the arms G G passes a bolt J, which has a thumb lever K screwed upon its threaded end.

H is a sole-piece having perforated lugs projecting from its back, by which it is pivoted 0n the bolt J, between the arms G G. The face of the sole-piece bears a pad, as shown in Fig. 10, to prevent abrasion of and increase its adhesion to the piano-cheek, against which it normally rests.

In placing the frame-board with its attached mechanism upon the musical instrument the spring-arms G G are turned toward the front and middle of the board on their pivots in the lugs projecting from the angle-plates M, as shown in Figs. 8 and 10, against the pull of their helical springs L, by passing the fingers under and pulling upon the rods J at each end. The board is placed in position on the keyboard with the contact-levers, hereinafter to be described, resting upon their corresponding keys E and F. Each pair of spring-arms G G is then allowed to carry its attached solepiece flatly against the cheek O at the corresponding end of the piano, and the thumb-lever K, being turned at each end, secures the sole-pieces by clamping them between the com- ICO pressible arms G G in each case. As long as the angles of the sole-pieces H relative to the corresponding pair of arms G G remain unaltered the frame-board will remain correctly in position on the keyboard of the piano. It will be seen that this arrangement allows of the same recording-instrument being used upon pianos of which the keyboards difierin length within certain limits. \Vhen the frameboard is removed, the spring-arms G G fold behind it, the sole-pieces H resting flatly against its back, provision of course being made to prevent their comingin contact with any of the mechanism secured thereto. Other suitable means of clamping the frame-board in the aforesaid position may, however, be adopted.

Upon the back of the frame-board are secured hangers O O by means of binding-screws O 0', Figs. 1 and 8, and these hangers hear at their lower ends fulcrum-screws 0 0 upon which turn flat contact-levers P P. These levers P P are given a tendency to turn downward toward the keys E E F F by means of springs similar to O bent round the fulcrumscrews 0 O and secured to the lever by turning up one end of the spring to form a short projection O, which enters a perforation O in the contact-lever.

The other end of the spring is secured to the hanger O in a similar manner. When two contact-levers turn in opposite directions upon a single fulcrum-screw, a spring is secured in a similar way between them. This is the case at P in Fig. 1, where it will be observed also that hangers are dispensed with and the fulcrum-screws enter the frame-board itself. By deflecting the hangers the positions of the contact-levers may be adjusted to suit variations in width of keyboard'which may arise from any difference in the keywidth used by various makers. Those variations which occur in the positions of the black keys with respect to the white ones are also provided for by this arrangement.

There are fulcrumed upon the back of the frame-board Aas many of the contact-levers P P as there are keys E E F F of which the action is to be recorded; but it has not been thought necessary in the drawings herewith to show more than one octave, as all the others are exactly similar in form and action.

In a suitable part of or projection from each contact-lever P is secured a wrest-pin O in such manner by riveting or otherwise that it turns stifliy when a screwdriver or suitablyformed key is applied to its free end.

Brackets Q Q are secured to the upper part of the frame-board A by screws which pass through lugs Q Q. These brackets Q Q carry a comb R having leaf-like teeth, between which pass thin marking-levers R, pivoted on a rod R lying in a series of notches R cut downward into the leaves of the comb. Openings are made in the brackets Q Q, so that the rod B may be wholly or partially withdrawn endwise from the comb R to allow of aleverpivoted therein being removed without disturbing the rest. Said comb may be formed in any convenient manner either by building it up from separate pieces or bycutting a series of kerfs in a solid bar. It is fastened to the brackets Q Q by screws, the head of one being shown in dotted lines beneath the slide Z in Fig. 3.

To the shorter arm of each marking-lever R is attached a cord or flexible wire R which is carried down and secured to the wrest-pin O in a corresponding lever P. The marking-levers are made in two sets having the holes for attachment of the cords R at different distances from the pivot R Said levers are arranged in the comb R alternately from each set, as shown in Fig. 2, in order that neighboring cords may clear each other near the points of attachment. As in nearly all cases it is necessary to change the direction of the cord or wire at some point in its course, this is done by passing it partially round a grooved pulley R, as is shown in Figs. 1 and 8, the former figure also showing that the pulleys R are arranged closely together as far as possible. in order that the edge of one may prevent the wire or cord which passes round its neighbor from slipping out of its proper groove. The pulleys are preferably mounted, as shown in Fig. 1, on pins fixed" in strips of metal R which are afterward screwed to the frame-board A. The longer arm of each marking-lever R carries a pin on one side, which forms a pivot for a marking-disk R. Said marking-disks rest normally upon an inking-roller S pivoted between the brackets Q Q The brackets Q Q also carry a rol of paper S to be used in making the record, which roll is supported on hooks Q Fig. 1, but shown more clearly in dotted lines, Fig. 8, a ruling-roller S which makes contact with the paper S and prints thereon the continuous staff and dotted leger lines shown in Fig. 2, being inked by the roller S an impression-roller S, partially round which the paper S is carried, and a roller S, intended to keep the paper from contact with the rollers S and S on its way to the impression-roller.

In Figs. 1, 2, 8, and 9,8 are marginal guides, each held in place by a screw S which guides assist in starting the paper band correctly on its way round the impression-roller. From the outer edges of the guides S are turned back lugs S in which is pivoted a rod S bearing rollers S intended to clip the paper in contact with the impression-roller S, thus securing its continuous movement therewith. The object of pivoting the rollers S in this manner is that their pressure on the impression-roller may be adjustable and elastic.

On the outer side of one of the brackets Q is mounted a spring-drum T, which maybe wound by the squared end T projecting through and supported by a bracket T Figs. 1 and 2.

T is the usual ratchet, and T the detent pertaining thereto, which is kept in place by a spring or by a counterpoise, as shown. The motion of the spring-drum is transmitted by a pinion T and rod T to a train of wheels mounted on the outside of the other bracket, as shown in Figs. 2 and 3. Of this train the wheel W gives motion to the pinion W,

mounted on the impression-roller journal, which thus obtains rotary movement and transmits the same to the rollers S and S by means of toothed wheels T at the other end. The outer pivots of the train-wheels V and W are carried by a narrow plate W which is held at one end upon a hollow post W by a shoulder formed on a post f and at the other end on a hollow post WV by a screw, both screw and postf entering the bracket Q.

The speed of the train is controlled by a flying governor constructed as follows: The wheel W which is the last of the train, gears with a pinion U and thus rotates a spindle U. In this spindle is formed a longitudinal groove U and upon it a helical thread U as shown in Figs. 2 and 4. U is a hollow roller having a stud U which enters the groove U so that the roller U can only have a sliding movement relative to the spindle U. Within the roller U and surrounding the spindle U is coiled a helical spring U To opposite sides of the roller U are attached the inner ends of ribbons U which ribbons may be' made, preferably, of metal foil;. but a somewhat stiff thin woven fabric or tough paper will in most cases serve almost equally well, save in respect of durability. The roller U is inclosed within a cylindrical case U and the free ends of the ribbons U pass out through corresponding slits U formed in opposite sides thereof. Through the solid end U of the case U is cut a thread, which isa counterpart of'that on the spindle at U The other end of the case is closed by a disk U which is perforated for the passage of the spindle U and has crown ratchetteeth formed on its outer face, as shown. A pair of parallel ribbon-supporting wires U is attached to each side of the case and project outward therefrom near the sides of the slits U therein. Each pair of supporting-wires U passes through guide-hooks formed on a clasp attached to the outer end of each ribbon, as at U or through loops form ed in the ribbon end itself, as shown at U in Figs. 6 and 7. Upon the spindle U is placed a sliding sleeve at, having teeth formed upon the end a opposed to the ratchet-disk U This sleeve ais kept from turning on the spindle U by a stud a which enters the groove U but its lateral position thereon may be altered by movement of a lever 12, of which the forked end I) engages the annular groove a, as shown in Figs. 2 and 4. The helical spring U is attached at one end to the hollow roller U within which it lies, and at its other end to the ratchet-disk U its tendency being to turn the case U, with the attached parts, in the direction toward which the fly normally turns when set in motion. (Shown in Fig. 5 by the curved arrow.)

This rotary movement winds the ribbons one on the other round the hollow roller U while the case travels laterally along the spindle away from the sleeve a owing to the helical thread U The ribbon-roller U also moves with the case, being pushed along the spindle by the back of the ratchet-disk U It will be seen that the mouth of the central hollow in the roller U is closed by and turns upon a shoulder formed at the back of the crown ratchet-disk U Normally a portion of each ribbon end protrudes through the slits U in the case U and when the train is set in motion the resistance of the air against these ends U is sufficient to overcome the tension of the spring U and the case U consequently rotates upon the spindle, carrying the ratchet-disk U spirally forward until its teeth meet and interlock with the similar ones opposed to it on the sleeve a. The rotary movement of the case U relative to the spindle U is now arrested, and the ribbons, which have been more and more unwound, as a consequence thereof cannot be further protruded without altering the position of the sleeve a by moving the lever b. The protruding rib bon ends form the vanes of the fly, and as their spread is clearly governed by the position of the lever 19, that lever is used, as will presently be shown, to regulate the speed of the motor-train. Upon stoppage of the motortrain the spring rewinds the ribbons within the case U As the fly-vanes make their minimum speed at the beginning of motion, the motor-train is enabled the more quickly to overcome the inertia of the moving parts and ride to the maximum speed allowed by the regulating-lever b. More than two ribbons may be used in constructing the fly, if desired.

In Fig. 6 is shown avariation from the construction just described. Here the ribboncase U turns upon but has no lateral movement relative to the spindle U, it being limited in this respect by the collar U and the ribbon-roller U", which are both fixed upon the spindle. The spring U is fastened at one end either to the roller, within which it lies, or to the spindle itself, and its other end is connected with the case, to which it gives the same tendency to wind up the ribbons'as in the other construction just described. The ratchet-disk now becomes a sleeve having a thread cut within it to fit the one on the spindle and also bearing pins or studs U which project through the slits in case U, the latter being made somewhat longer than that before described. As thus arranged the case simply rotates under spring-tension or air-pressure, while the crown ratchet-sleeve U alone has the spiral movement along the spindle U relative to the annularly-grooved sleeve a. This construction may be somewhat simplified, when the spindleU is of sufficientlength, by placing the spring U upon the spindle behind the case U near the fixed collar U In this arrangement the ribbon-roller may be III) dispensed with and the vane-ribbons wound directly upon the spindle, a collar, such as U in Fig. 7, being placed within the case to prevent lateral forward traverse.

In Fig. 7 is shown still another modification of the fly construction which may be adopted without departing from the nature of my invention. Here the case U is fixed upon the spindle U, while the ribbon-roller has a simple rotary movement relative thereto, its lateral traverse thereon being prevented by the fixed collar U within its cavity. The crownratchet is connected with the roller U in the manner already described with reference to the case U in Fig. 6, while the spring U fastened at one end to the collar U and at the other to the roller U always tends to wind the ribbon within the case; butinstead of airresistance it is in this construction the pull of centrifugal force upon the normally protruded ends that unwinds the vane-ribbons when the train is set in motion. In order to prevent jamming when the ratchets interlock, the teeth upon the disk U and sleeve 0., or upon one of them, should be so formed that their backs are parallel with the spiral threads of the screw U Instead of a complete set of ratchet-teeth being formed both upon the disk U and sleeve a a single tooth upon one of them can be used, as shown ata in Fig. 7.

The constructions shown in Figs. 6 and 7 require no longitudinal groove in the spindle U if that part of it marked U upon which the sleeve a slides, be squared. The fly is pivoted at one end in the bracket Q and at its other and outer end in a plate 6, Figs. 2 and 3, said plate being partially broken away in the latter figure to show the parts beyond. This plate 6 is supported by the postsf, f, and f which project from the train-bearing bracket Q. In the postf is pivoted the upper end of a rod m, of which the lower end is carried by a hollow formed in the tip of a screwone of two marked '0 o in Fig. 12. Near the upper end of this rod m is rigidly fixed a lever 92, having a loose stud 19, one arm of which stud p is connected by alink W made of wire, with another similar loose stud N in the arm W attached tothe pivot of the wheel W and pinion W as shown in Figs. 2 and 3. In consequence of this connection the lever n is reciprocated as the arm 7 rotates when the train is in motion. Another arm of the lever n, which is marked at, carries a screw V and upon the projecting part of this screw V below the arm n, is screwed loosely a collar V. In this collar is pivoted the forked end of a link V, Fig. 12, of which the other end is bent upward and screwed through a loose stud V in a Y-shaped carrier V swinging upon a screw V fixed in the frame-board A.

The screwed collar V, turning on the screw V in arm n, is used as a convenient means of insuring that the link V shall turn upon the same vertical axis as a lever X presently to be described. This lever should be approximately in line with the axis of the stud V in the carrier V The body of the link V is preferably screwed into the fork which forms one of its ends in order that any slight variation in its length that may seem desirable can be easily made. In the Y-shaped carrier V is a vertical rod V upon which is fixed a sleeve V bearing a pinion V, Fig. 8, the object of the sleeve being to keep the rod V in place. In the upper end of the rod V the arm V is hinged on a pin V, passing through them both. This arm V beats back and forth after the manner of a metronomearm when the train of wheels is in motion, owing to the reciprocating movement of the lever n being transmitted through the link V to the hanging carrier V The arm V is made of light and thin material, so that its normal edgewise oscillation may meet with but slight resistance from the air. The purpose of the hinged connection of the arm V with the rod V is to permit of the arm being turned down below the edge of the frameboard A when the recording apparatus is not in use or is being moved about. The friction between the arm V and the sides of the slot in which it turns is sufficient to keep it in line with the rod V when turned up.

The pinion V is engaged by a toothed segment X Fig. 2, terminating the longer arm of a lever X, which lever is pivoted on the screw V in arm n of the reciprocating lever a, and consequently moves bodily therewith.

The shorter arm of the lever X is slotted at X for the passage of the rod on and is notched at X for a rod g, rising from an oscillating fork h h, which is integral with and projects from a slide K, mounted freely upon the rod m, bearing the reciprocating lever n, Figs. 3 and 12. Within the oscillating fork h h and between pins j j, projecting therefrom, rotates the edge of a wheel IV, forming one of the motor-train. This wheel has several concentric rows of pins J projecting from its sides. Upon the rod m is mounted a slide Z, as is shown most clearly in Fig. 12, which slide Z supports the slide 70, carrying the oscillating fork h 71, being itself supported by a projection Z, resting on a slide 4'. Movement of this slide 1" is made to regulate the height of the oscillating fork h h, so that the pinsj j may be brought opposite the path of any one of the rows of pins j j in the sides of wheel W. The pins jj in the wheel W are so spaced in each row that one may be brought opposite one of those in the fork h h at regular intervals, which intervals correspond for each row with a different fixed number of beats of the metronome-arm V. This result is secured by giving the arm W a certain suitable rate of speed relative to the wheel W. In the present case the arm W makes eighteen revolutions for every one of the wheel W, and as a consequence thereof the arm V makes thirty-six beats in the same time. This number thirty-six is a common multiple of the intervals of two, three, four, six, and nine beats, respectively, provided in the machine shown in the accompanying drawings. This invention, however, is not limited to these five intervals, but the number may be either diminished or increased by a suitable alteration of the size and relative speed of the train-wheels, the rows of pins jj' and adjustable positions of the fork h h being made to correspond therewith. The pinsjj in those rows on wheel W which correspond with intervals having an odd number of beats should be arranged alternately on opposite sides. A shaft X turningin the brackets Q Q, carries a segment X", from which project radially the pins X Fig. 9. At X in the longer arm of the lever X is pivoted a Y-shaped link X, and of the ends which form its fork one has a closed slot for the passage of the upper pin X and the other a similar slot left open at its outer end for the lower pin X The upper slot is shown clearly in Fig. 2. The parts are usually in the position shown in Figs 1. 2, 9,and 12, and as a consequence thereof it the toothed arm of lever X be moved inward from the frameboard the segmentX and shaft X are pushed round by the lower pin X which rests at the inner end of the open slot, and if the toothed arm be moved outward toward the frameboard A the segment and shaft are pulled round by the upper pin X resting at the outer end of the closed slot shown in Fig. 2.

The shaft X is always rotated in the same direction to whichever side the toothed arm may swing from its normal central position. A link X connects a pin X in the side of the segment X with a time-lever X, as is shown in Figs. 1, 9, and 12. This lever X is pivoted on the rod R and its weight being transmitted to the lever X through the Y- shaped link X serves to return that lever to its central position after a sidewise oscillation. This sidewise movement will be presently referred to again and its cause shown.

Instead of linking the lever X directly with the segment X, as already explained, the construction shown in Figs. 15 and 16 may be adopted withoutdeparting from the nature of my invention. In these figures the lever X is connected with a loose stud in another lever X by a wire link X similar to the link W joining the arm W with thelever n. The wire is passed through stud X and is then bent, as shown in Fig. 15, so that its ends may be sprung into holes made in opposite sides of the stud X The lever X has a sleeve or boss at its lower end, through which passes a screw X serving to pivot it on the train-bearing bracket Q. The tappets X 7, bent up from the edges of the lever, replace the slots formed in the link X already described, but-have precisely the same function and effect in rotating the segment and shaft by the pins X", which ,in this case project sidewise instead of radially therefrom. The

pin X is to carry the link X as in Figs. 9

and 12. The lever X is slotted at x ro'r the passage of the shaft X By looking at Fig. 9 it will'be observed that the weight of lever X, acting through the link X and pins X has a tendency to throw the single end of link X upward, thus deflecting the toothed arm of lever X in the same direction. This deflection is only material in so far as it slightly increases the friction at the points of connection between levers X and n. By adopting the construction shown in Figs. 15 and 16 this deflection is avoided, but a little is lost in simplicity. However, when it is desired to place the shaft X so far above or below the level of lever X that such a link as X cannot be easily used the intermediate lever X may replace the link X with advantage. The link X or link X", as the case may be, is of such length relative to the radius of arm n that no material sidewise deflection of the toothed segment X occurs as a consequence of the endlong reciprocation of the lever X as the ordinary time-beats are being made.

The free end of the time-lever X extends below the impression-roller S, as shown most clearly in Fig. 9, and carries on each side type-segments X bearing type-figures, of which some are shown in Fig. 2. The typesegments are pivoted on a rivet X and are connected, as shown in Fig. 9, by light linkbars X with corresponding levers X and X, which levers are pivoted on a screw X projecting from the neighboring train-bearing bracket Q. Springs X hold the upper ends of the levers in contact with the edges of two related slides (marked a" and s) lying in a groove A, formed in the middle part of the frame-board A. At g Fig. 2, in dotted lines, are shown the stepped edges of these slides, which actuate the levers X and X to set the time-fractions. From the slide ra tongue 0" is turned upward, and from the slide 8 a similar tongue 8' is turned downward, as shown in Figs. 9 and 12. These tongues r and 3' form indices which show upon the corresponding scales t and u the lateral position of the slides. Notches A A Fig. 9, are out through the frame-board A behind the scales i5 and u to allow of the slides r and .9 being inserted in the groove A after the indextongues r and s have been formed on them. The slides are firstinsertedin the groove and the scales afterward slipped behind the indices and fastened by the screws, as shown in Fig. 12.

The numerals upon each scale agree with the type-figures upon a related one of the type-segments X and these figures represent in one case the denominators and in the other the numerators of the time-fractions commonly seen at the beginning of the staff in music. The slide '1", which, acting upon the lever X adjusts the numerator type-segment, carries the stepped edge q. Upon this edge is supported the tongue Z, forming part of the fork-adjusting slide 1, which slide Z is kept from turning on the rod mby the entry of its IIO tongue Z into the verticalgroove A provided .for that purpose in the frame-board A, Fig. 3. The steps on the edge (1 are so regulated that when the tongue Z rests on one of them the pinsjj in the fork h h are brought opposite a corresponding row of pinsjj on the wheel TV. The slide .9, which, acting on the lever X adjusts the denominator type-segment, also carries an edge q, Figs. 2 and 3, having as manyinclines thereon as there are numbers on the corresponding scale 10. Against the edge q rests the end Z2 of the lever b, under impulse from a spring 0, attached at one end to a hook fixed in the plate 6, Figs. 2 and 12. The lever Z) is carried by a rod d, turning in the postfand screw 7., being mounted similarly to the rod m. The spring 0 may be replaced by a helical spring coiled on the rodb if it be desired to make room for a greater spread of the governing-fly than that shown herein. Each of the inclines on the edge q is at such an angle that as the end Z) rides along it the fork of the lever 1) moves the stopsleeve a through a certain range, which may be the whole or only a part of its whole range of lateral movement on the spindle U.

The inclines on g are opposed to each other in order to avoid havinga considerable jump in passing from one to another. A ratchetwheel Y is mounted loosely upon the journal S of the impression-roller S; but its rotary movement relative thereto is limited by a pin Y, which is fixed in the Wheel V7 and projects through the curved slot shown in Fig. 11, the pin Y forming both a back and front stop. Upon the boss of the ratchet-wheel is mounted a weak spring Y of which the free tongue presses against the pin Y, and thus gives the ratchet Y a tendency to turn forward in the same direction as that in which the impression-roller usually rotates.

Y is adetent so mounted on a screw Y (shown in section in Fig. ll) as to engage the ratchet-teeth and connected byanotch in the end of a rigidly-attached arm Y with a rod Y as shown in Figs. 2 and 11. The rod Y lies across the upper edges of the markinglevers R and forms with the ends Y Y a universal bail turning on the rod R Owing to the detent Y engaging the ratchetwheel Y the motortrain and connected parts are at rest until a key E or F is struck and is followed downward by a contact-lever P under theinfiuence of spring 0 bent round its fulcrum-screw 0 This movement is transmitted along the cord or wire R to the corresponding marking-lever R, which in carrying its attached marking-disk R from the inking-roller S against the paper S on the impression-roller S raises the bail-rod Y and detent-arrn Y thus removing the detent Y from the teeth of ratchet-wheel Y.

VtThen the depressed key E or F rises and the connected markinglever R returns to its normal position, the detent Y again enters the teeth of wheel Y; but as that wheel has been in the meantime thrown forward on the journal S by the spring Y the motion of the train is not at once arrested, but continues until the pin Y arrives again at the forward end of the curved slot in the already-stopped ratchet-wheel Y. This interval between the return of a note E orF and the total stoppage of the motor-train and connected parts bridges any ordinary complete pause likely to occur in music and prevents waste of paper. Such pauses or the more common rests are indicated on the paper band by the appearance of a pronounced interval between the end of one and the beginning of the following notemark.

Referring to the torn record in Fig. 2, the positions of the note-marks upon the staif approximate to those of the same notes as usually written, note-marks made by white keys appearing upon or midway between staffline sand those resulting from movement of black keys immediately above or below stafflinesthat is to say, slightly above or below the note-marks made by white keys, of which they are the sharps or flats, as the case may be. This result is secured on a staff having lines uniformly far apart by arranging the marking-levers connected with white keys at equal distances apart in the comb R, even though the corresponding notes differ in pitch by a half-tone only, as in the case of E and F, B and O. This arrangement is apparent in Figs. 1 and 2. The duration of a note is indicated by the comparative length of the related line marked upon the paper band, and in order to facilitate comparison of one mark with another in respect of length when copying the record vertical lines are printed or ruled across the paper at equal intervals, as shown in Fig. 2, before the band is madeinto a roll. While music is being played the metronome-arm V beats at a rate dependent upon the speed at which the fly U has been set by movement of the denominator-slide s, and the figure in printing position on the connected type-segment X will be that of the division on scale to, in which the indicator-point s rests. The number of beats to the measure is fixed by the position of the numerator-slide 4", which acts upon the slide Z and oscillating fork h h, and also through the lever X and link-bar X sets the related type-segment so that the figure in printing position thereon agrees with the number of the division on scale 25, in which the index-point r rests. When the metronomearm V is finishing the last of the beats allotted to a measure, a pinj on the wheel 7 arrives in the path of one of the pinsjj, carried by the oscillating fork h 71, and arrests its movement, which movement results from the passage of the pin gupward through the slotted arm X of the toothed lever X. The slotted arm X being thus also arrested, while motion still continues in the reciprocatinglever 12, the toothed arm of lever X is necessarily swung to one side, which movement causes the toothed segment X acting upon the pinion V to give the metronome-arm Va half-turn to indicate that a measure is complete.

hen a pin j is stopped by a pin j, their ends should preferably remain in contact during a full half-turn and return of the arm V. This result can be secured by making the sizes of the pins j j proportional to their relative distances from the axis of wheel \V. The said sidewise movement of the lever X at the same time, through the Y- shaped link X pulls or pushes the shaft X round, thus causing the link X and time-lever X to raise the type-segments so that the set time fraction is printed on the paper margin, as shown in Fig. 2, the mark dividing the two figures being made by the point X, forming part of the time-lever at. This time fraction on the paper margin thus shows the contents of a measure and also indicates the place of the dividing-bar.

The type-figures are inked in the following manner: A lever of the form shown at X in Fig. 9 turns upon the pivot X of the typesegments and has a notch S through which passes in this case the pivot of the inkingroller-S but a pin fixed in the neighboring bracket Q may be employed instead. On one side of the lever X, at its upper end, are mounted a pin X and a small inking-roller X around which pin and roller passes an endless tape X This tape conveys ink from the roller X to the type in printing position, normally making contact therewith near the pin X but when the time-lever rises at the end of a measure the arm X turning upon the pivots X and S is thrown backward out of the path of the rising type-segments X Friction between the face of the type and the endless tape tends to give the latter a slow movement round the pin and roller, so that a fresh inking-surface is being constantly presented to the type. In order to secure a clear impression of the time fraction on the margin of the paper band, the type-surface is allowed to move with the paper during the short time they are in contact.

The link X is connected with the related segment X by a pin in the latter, which passes through an elliptical slot in the former, thus making a somewhat loose connection between them, as is shown in Fig. 9. 'When the inking'arm X is thrown outward, owing to upward movement of the time-arm X,.the friction of the inking-tape X tilts each type-segment until the fixed pin therein rests at the outer end of the elliptical slot through which it passes. Upon bringing the type against the paper band S the segment X is carried backward in contact therewith, the fixed connecting-pin moving toward the inner end of the elliptical slot in the link-bar X The type-segments X may be dispensed with and a mark made by the point X of the lever X used to show the place of the bar alone, or a pair of levers may be used to make a mark on each margin, and in this case the denominator-segment may be attached to one and the numerator-segment to the other, so that a figure may be printed on each margin of the band S The sections of scale t0 may be divided, if desired, so that the motor-train may be at once set approximately at a predetermined rate of speed, so that the arm V may make a particular number of beats to each minute.

I preferably make the metronome-arm V with sides differing in color, as in Figs. 1 and 12, so as to show more distinctly the turn which marks the end of a measure. In Figs. 13 and 14 are shown the means employed to secure audible time-beats in conjunction with the beating-arm V or otherwise. In Fig. 13 is shown two bells Z Z, mounted at the ends of the hanging strips Z Z, so that their positions may be adjustable relative to the corresponding hammers Z Z on the hanging arms Z Z united with the arms Z Z by the bosses or sleeves Z Z through which pivotscrews pass into the f rams-board A. Through each arm Z passes a pin or rivet on which turn the trips Z bent up from sheet metal, as shown in Figs. 13 and 14. The pin V in Fig. 13 projects on one side only and as the rod V moves back and forth comes in contact with one of the trips, tilting it up on its pivot Z in the arm Z until the edge of the bend Z strikes the edge of that arm.

As the rod V continues its movement, the trip-point Z rides across the pin V, carrying the arm Z up, thus raising the bell-hammer Z Near the end of sidewise movement in red V the trip slips over the pin V, allowing the hammer to fall and sound the bell. When the lever X is deflected at the end of a measure and the rod V is rotated by the toothed segment X acting on the pinion V the-pin V is carried round and acts in the manner just described upon the trip connected with the other hammer, causing that closing beat to be struck upon the fellow bell, which I make of a distinctive tone.

In Fig. 14 the pin V is shown projecting on both sides of the rod V and the beats are all made on a single bell. That end of the pin V which turns to cause the closing beat should be slightly farther projected than the other, so as to be sure and catch the trip from its central position. The side to which the pin V normally projects in the two-bell construction of Fig. 13 and the side ,on which the bell-trip is placed in the one-bell plan of Fig. 14 should be such that when the last beat of a measure is being produced, at the time of its contact with the hammer-trip, the movement due to the rotation and that due to the tilting of rod V may both be carrying the effective part of pin V in the same direction.

In Fig. 17 is shown a somewhat different arrangement in relative position of the paperroll, ruling-roller, and impression-roller, by which the roller S and the clipping-rollers S may be dispensed with. g

It will be observed that the ruling-roller is inked by a separate inking-roller S and that the disk-inking roller S is rotated byatoothed i spring pressure, substantially as and for the wheel gearing with the pinion T on shaft T as shown in dotted lines. The paper after passing partially round theimpression-roller S is allowed to rest on the paper-roll, being thus conveniently carried away. Paperguides, such as S take the place of the ones shown at S in Figs. 1, 2, 8, and 9.

The-height of the piano front D will to a great extent decide whether the arrangement of Fig. 8 or that of Fig. 17 is the better one in any particular case. If necessary, the recording mechanism maybe put at one end of the frame-board instead of in the middle, and the height may be reduced, if so desired, by placing two or more of the pulleys R on the same pivot-pin. The train-bearing bracket Q is cut away at Q Figs. 3 and 12, for the passage of the slides, the forked link, the lever X and the rod Y.
